The incident occurred at the Baltimore Gas and Electric (BGE) building, according to a tweet from the Baltimore City Fire Department.
The incident is probably related to construction, not natural gas, and occurred while teams worked on the building’s air and boiler treatment system, a BGE statement said.
The building was practically empty because of the upcoming holiday and the pandemic, according to the statement, and the Fire Department and BGE teams will continue to investigate.
According to the BGE statement, the window washing scaffolding has been compromised and a window washing team has been pulled to a safe place by the fire department.
The official cause is currently unknown, says a tweet from the fire department.
